Maintenance and care
Wheels
■When replacing wheels
The wheels of your Lexus are equipped with sensors that allow the tire pressure
warning system sensors to provide advanced warning in the event of a loss in tire
pressure. Whenever wheels are replaced, the tire pressure warning valve & trans-
mitters must be switched over from the old wheels. (→P. 2 9 9 )
If a wheel is bent, cracked or heavily corroded, it should be replaced. Oth-
erwise, the tire may separate from the wheel or cause loss of handling con-
trol.
■Wheel selection
When replacing wheels, care should be taken to ensure that they
are equivalent to those removed in load capacity, diameter, rim
width, and offset.
Replacement wheels are available at your Lexus dealer.
Lexus does not recommend using:
• Wheels of different sizes or types
• Used wheels
• Bent wheels that have been straightened
■Aluminum wheel precautions
●Use only Lexus wheel nuts and wrenches designed for use with
your aluminum wheels.
●When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
●Be careful not to damage the aluminum wheels when using tire
chains.
●Use only Lexus genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.
●Never use an inner tube in a leaking wheel which is designed for a tubeless tire.
Doing so may result in an accident, causing serious injury or death.
NOTICE
■Replacing tire pressure warning valve & transmitters
●Because tire repair or replacement may affect the tire pressure warning valve &
transmitters, make sure to have tires serviced by your Lexus dealer or other qual-
ified service shop. In addition, make sure to purchase your tire pressure warning
valve & transmitters at your Lexus dealer.
●Ensure that only Genuine Lexus wheels are used on your vehicle.
Tire pressure warning valve & transmitters may not work properly with non-genu-
ine wheels.
